The team led by Claes Ohlsson of the University of Gothenburg hypothesized that loading the vests with weights would lead to a compensatory reduction in body weight.
To verify this, they examined 69 people with a body mass index (BMI) of 30 to 35.
The instructions for the participants were to wear a weight vest for eight hours a day for three weeks and live as usual.
Portable weight vests can help reduce weight and fat mass, the Swedish research team reports from the results of their research.
The corresponding study was published in the English journal “EClinicalMedicine”.
Wearing weight vests can help you lose weight.
According to a recent study, this is an effective way to reduce body weight and fat mass.
The vest is worn during the normal daily routine over a period of several hours.
How was the study structured?
Lose weight wearing weighted vests?
All participants wore weight vests during the exam.
At the start of the study, participants were assigned to one of two groups.
The control group wore only light vests weighing one kilogram (kg), while the other group wore heavy vests weighing approximately eleven kg.
After three weeks, people in the normal group, who were wearing the heaviest vests, had lost 1.6 kg.
In comparison, people in the control group lost only 0.3 kg.
69 people wore a weighted vest for three weeks
Wearing heavy weight vests not only reduced fat mass, but muscle mass also remained intact.
The researchers report that the effects on fat mass seen in this short experiment exceeded what is normally seen after various forms of physical training.
But the researchers couldn’t determine if it was a reduction in subcutaneous fat (just below the skin) or the dangerous visceral fat (abdominal fat) in the abdominal cavity, which is most associated with cardiovascular disease and diabetes. .
The researchers have yet to answer many questions about how the so-called gravitostat works.
One of the aspects they would like to investigate in the future is whether changes in energy consumption, appetite and mobility will help people in vests lose weight.
The research group is also trying to determine if weight loss in western users continues for more than three weeks and if the treatment reduces dangerous visceral fat.
(how)
If people spend a lot of time sitting, the value on the internal scale appears to be too low.
According to the researchers, this could explain why long daily periods of sitting can be so clearly associated with obesity and health problems.
Weighted vests can increase the reading on the internal scales, leading to weight loss.
In previous animal studies, published in 2018, researchers showed that there is an energy balance system, which they call a gravitostat, and that it strives to keep body weight constant.
In mice, this regulation takes place, among other things, by influencing appetite.
To function, the system must have some kind of scale, explains the research group.
The new clinical study shows that there are similar “integrated scales” in humans.
